Command:

set vtp pruneeligible

Mode:

Switch> (enable)


Syntax:

set vtp pruneeligible vlans


Syntax Description:

vlans

Variable that specifies the range of VLAN numbers; valid values are from 2 to 1000.

 


Command Description:

Use the set vtp pruneeligible command to specify the VTP domain on which VLANs are prune eligible.

VTP pruning causes information about each pruning-eligible VLAN to be removed from VTP updates if there are no stations belonging to that VLAN on a particular switch port. Use the set vtp command to enable VTP pruning.

By default, VLANs 2 to 1000 are pruning eligible. You do not need to use the set vtp pruning command unless you have previously used the clear vtp pruning command to make some VLANs pruning ineligible. If VLANs have been made pruning ineligible, use the set vtp pruning command to make them pruning eligible again.

 


Examples:

This example shows how to configure pruning eligibility for VLANs 120 and 150:

Console> set vtp pruneeligible 120,150

Vlans 120,150 eligible for pruning on this device.
VTP domain nada modified.
Console>
 

In this example, VLANs 200 to 500 were made pruning ineligible using the clear vtp pruning command. This example shows how to make VLANs 220 to 320 pruning eligible again:

Console> set vtp pruneeligible 220-320

Vlans 2-199,220-320,501-1000 eligible for pruning on this device.
VTP domain Company modified.
Console>
